Abstract:

Traditional supercapacitors have low energy density, which in most cases hinders their further practical applications, therefore, people more focus on studies of the structure-composition-property relationship of electrode materials towards high performance supercapacitors during present research and development of electrochemical energy storage devices. This article summarizes the history of research and development of novel supercapacitors, as well as their challenges and strategies, with the aim to find novel supercapacitor systems via searching for high efficient electrode materials and electrolytes. Novel electrode materials and redox electrolytes are thus particularly emphasized herein, for example, some promising electrode materials of colloidal ion supercapacitor systems have shown some advantages compared to those ex-situ prepared electrode materials, which indicates high electrochemical reactivity existing in the colloidal state of constituent transitional and rare earth metal cations. Furthermore, we also introduce novel lithium-ion supercapacitors as some promising research and development directions. On the basis of the current status of research and development of supercapacitors, it is highly expected to combine the advantages of both battery electrode materials and supercapacitor electrode materials towards the so-called supercapattery or supercabattery, which may be dominant in the field of future electrochemical energy storage devices.
